ProgrammIng your s2 roBot
Your S2 robot contains a reprogrammable "brain," the Parallax Propeller P8X32A-Q44 multi-
core microcontroller. This Propeller P8X32A-Q44 chip comes pre-programmed with the 8
Demo modes shown in this guide. You can also write your own custom programs on your PC,
and download them to your S2 robot through a programming cable (sold separately, see Sys-
tem Requirements).
Beginners can program in picture blocks with the S2 GUI (Graphical User Interface) program-
ming software. Those interested in learning more about the Propeller and taking full advan-
tage of the many additional possibilities of the S2 robot should download the Propeller Tool
code editor from www.parallax.com/go/S2. By programming the S2 directly with the Propeller
Tool Code Editor you will have access to the hacker port. The hacker port can be used for RF
devices, ultrasonic sensors, passive infrared sensors and anything else you wish to attach or
power from your S2 robot. Page 27 includes a variety of helpful S2 resources.
